What is the area of the rectangle ABCD?

Video Solution

Solution Steps

00:00 Determine the area of the rectangle ABCD
00:03 Opposite sides are equal in the rectangle
00:09 The line intersects the side according to the given data
00:16 The entire side equals the sum of its parts
00:22 Apply the formula for calculating the area of the rectangle
00:25 Side(AB) multiplied by side(BC)
00:28 Insert the relevant values into the formula and solve to find the area
00:31 This is the solution

Step-by-Step Solution

Given that in a rectangle every pair of opposite sides are equal, we can claim that:

AB=DC=8 AB=DC=8

and also:

BE=EC=2 BE=EC=2

In other words, BC equals 4

Now we can find the area of the rectangle by multiplying the length by the width:

AB×BC=8×4=32 AB\times BC=8\times4=32

Answer

32 cm²
